I’ve started a new security company together with @claudijd: Asymmetric Research (@asymmetric_re / asymmetric.re ). If you are a strong security engineer or researcher interested in defending and breaking some of the biggest DeFI and Blockchain projects, we’d love to chat. DM’s are open.

We found the same Fiat-Shamir bug in six independent zkVMs. The result: an attacker can bypass the cryptography entirely and prove mathematically impossible statements (like minting $1M out of thin air). Full breakdown ↓
